3/2+t=1/2 how to slove
Nataly [62]
First, let's isolate t! Make sure to change your signs when you change from one side of the equation to the other. 

3/2 + t = 1/2
          t = 1/2 - 3/2

Now, we can solve for t!
          
          t = 1/2 - 3/2
          t = -2/2
          t = -1

Hope this helps!
